EDGAR CHERRY, OF SAN FRANCISCO, CALIFORNIA.

ADVERTISING DEVICE.

SPECIFICATION forming part of Letters Patent No. 640,875, dated January 9, 1900. Application filed June 5, 1899. Serial No. 719,506. (No model.)

To all whom it may concern.-

Be it known that I, EDGAR CHERRY, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and usefulImprovements in Advertising Devices; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art to which it most nearly appertains to make, use, and practice the same.

This invention relates particularly to rotating mechanisms adapted to the actuation of advertising devices, for which Letters Patent of the United States were granted to me on the 4th day of April, 1899, bearingNo. 622,416, and will be described in connection therewith.

The object of the present invention is to provide automatic and simple means for rotating a wheel one-half revolution forward and back.

In the drawings, Figure 1 is a front elevation of an advertising device constructed in accordance with this invention, being partly broken away to show the operating mechanism. Fig. 2 is a side elevation of the operating mechanism. Fig. 3 is a front elevation of the same.

The advertising feature of the device consists of aseries of panels so connected together that a half-revolution of the end panel or the one designated in the drawing Fig. 1 as No. 1 will lift No. 2 to a position directly behind No. 1, when by the action of gravity and the peculiar hangings 2 will fall to a position behind 3, 3 will fall out over 4., 4 behind 5, and so on through the series, which may comprise any In the reverse rotation the panel No. 1 will resume its former position, drawing 2 up in front of it, repeating the former action, but exposing the reverse side of each panel which has shown in the rear of the device in an inverted position.

The present invention for producing the above efiects, described with reference to the drawings consists of a sprocket-chain, (designated by the distinguishing-letter A,) the sprocket-wheels A A the actuating means therefor, such as the motor B, and the sheavepulleys C and D, the former, C, engaging the sprocket-chain A by means of the pins A thereon and the pins C extending in a periph-' eral arc one-half the circumference of and alined on both sides of the sheave C, the latter, D,repeatin g the rotations of the former by reason of the belt connection E between them.

The motive power B is shown as an electric motor, it being obvious, however, that this may be substituted by a'spring-rnotor, waterwheel, or any other suitable means.

The motor B actuates the sprocket-wheel A through the reducing-gears B E the sprocket A transmitting motion to the chain A, the pins A thereon engage the pins C successively, giving a one-half rotation'to the pulley C, the chain, continuing over the wheel A returns, the pins A engaging the pins C on the opposite side of the pulley C rotate it backward to the normal position, one revolution of sprocket-chain A causing the exposure of both sides of each panel in the series, it being evident, however, that more than one series of pins A may be used to cause, if desired, quicker changes in the panels.

I have found it preferable to locate the actuating mechanism at the side of the device, as shown; but it may be, with a few slight changes, located horizontally across the top of the frame X and geared to the pulley D by means of a miter-gear without altering the spirit of this invention.

The panel No. 1 is secured to the pulley D by means of the socket D on the face of said pulley, the other end of said panel being pivoted upon a pin extending from the end of said panel engaging a socket on the side of the frame X. This socket D facilitates the removal and change of the series of panels.

The pulley C and belt E may be dispensed with by placing the pins C in the pulley D; but this would necessitate the raising of the sprockets A and A so as to time the changes of the panels equally, and detract from the appearance of the machine.

ating mechanism for said sprocket-chain sub 10 stantialiy as described.

In testimony whereof I have hereunto set my hand this 18th day of May, 1899.

EDGAR CHERRY.
